Thousands of people in South Sudan have been killed in violence and more than one million people have been forced to leave their homes since December when pro-Kiir troops and those loyal to Machar began to fight along ethnic lines.
The UN’s mission in South Sudan said on Monday hundreds of civilians were killed or wounded after rebel forces took control of the capital of the oil-producing Unity state last week.
Toby Lanzer, the UN’s top humanitarian official in South Sudan, said in Twitter posts late on Sunday that there were shocking scenes of atrocities, with “bodies of people executed” lying in Bentiu’s streets.
Lanzer told Al Jazeera on Monday that people “associated with the opposition” had used an FM radio station to broadcast hate speech in the town.
"With hate speech and violence continuing as they are, we’re going to have an even greater catastrophe on our hands at the end of this year," Lanzer said.
“I think the saddest testament to the current situation is that we have had members of all communities, even those accused of perpetrating these crimes, fleeing to the UN base,” he said.
"We had 5,000 civilians a week ago in our base, now we have 22,000 people. We have just one litre of portable water per person for today."
